The weakest castle in Heroes of Might and Magic IV!

Koren Zla, please provide some reasoning for your post, otherwise you will receive the same response as a couple of posts above (and quite deservedly, by the way). By "a couple of posts above," I mean

at least let them provide some arguments... But Death is stronger than everyone! Life is the weakest!!! I'm so tired of these kinds of posts.

As for the question, I think the Barbarians are the weakest (especially on large maps) due to the lack of magic and the unmanageability of the Berserkers.
Also, regarding the Barbarians - does anyone build Bear Riders (or whatever they're called)? I think the Bird Riders are much more effective.
P.S. Sorry if this is off-topic.
